ECU ideal temperature 850

posted by  someone claiming to be Yellow 850 on  Sun Jul 18 04:54 CST 2004 [RELATED]

I doubt that the (small) duct is flowing cold air, especially during traffic jam.

I put a styrofoam between the ECU housing and radiator reservoir. After a long drive, the styrofoam's temperature is low but the ECU housing is as hot as the radiator reservoir.
Next I will test disconnecting the air duct and see if the ECU box is cooler.

Is there a code for each ECU when they gone bad???
